BUBBLE-"Fou NTAIN.

Application 'filed Dct0ber 13 1903 Serial Not 176,834:-

ToaZ'Z whom it may-concern: I v Be it known that I, SAMUELTH. TACY, a citizen of the United States,v residing in the city and county of San Francisco and State of- California', have invented new and useful Improvements in-BubbleFountains, ofwhieh the following: is as V ecification.

My invention re ates to an imprQvedapparatusforcontinuously forming: bubbles. Its object is to provide" an apparatuswherfeby bubblesmay be blown continuously and in large quantities for producing various artistic effectsinsimulation-ofi waterfalls and' the like.

It consists of the partsand the construction' and" combination of morefu'lly described,havingreference to the accompanying drawings, in which- Figural is asectional view of my apparatus: Fig-V. 2 is: aplan of theoperating mechanism; Fig.- 3 is a modific'ationof the device.-

A represents a suitably supported conta'iner' or generating vessel of any desired size, shape, and material ada ted to receive a sapo'naceous or other suitab e bubble-formingsolution. Air from any convenient 7 source of sup ly, asthe blower 2, is. delivered through pipe 3 to the submergednozzles 4, which are here shown asadjii'stableJ Water is delivered under constant head tojt'he container through pipe 5 from reservoir 6 .by means'of the pump 7, which is driven in unison with blower 2 from the same motor 8.

- 9 is an overflow-pipe by which any excess of liquid discharged by the pump intov the container may be returned to the reservoir. Pipe 9 is provided with an adjustable section 10 whereby the desired level of the liquid column in the container may be varied within certain limits. By thus making the nozzles 4 and the outletof the stand-pipe adjustable I am able to regulate the depth of submergence of the nozzles to produce bubbles of dif-' ferent size and quality and to vary the quantity of the bubbles, since the volume of liquid not only affects the quality of the bubbles, but the deeper the nozzles are immersed the smaller and more numerous the bubbles will be. I The shallower the dipof the nozzles, the

liquid from reservoir 6 is forced by the pump into the container A. As soon as the liquid rises therein to submerge the nozzles 4 the air.

arts as hereinafter Fig. 4- is a sectional view on: line 00 r,

which is being forced through the nozzles from the blower starts the generation of the base of the container, and as'they condense the liquid flows back through suitable cha'ria nels' 12 tothe reservoir tobe usedover and over again. By themanipulation-of: colored lights and the direction of thebubble=flow numerous and varied: artistic efiectsiare possible, the natural affinity of the'bubbles-ifor each other and their attraction forany surface withwhieh they may come in contact assisting 'in this;

By the interpositionof: the pump the. v

supply-pipe leading from-the reservoir to t'he container and keeping the pump'in constant; I

operation during the bubble blowing; period and letting the overflow-pipe take'c-are of any :excess in the containerthe" apparatusisre'n- F dered; extremely simple and any danger" of the liquid in the container becomingireduced below a point as would-'cause a' cessation in operations is avoided-.7

The principle of the a paratus above ole-j scribed is capable of appllcationto avarietya of forms of mechanism. In Figs. 3 ands-I have shown amodificationsliggestive of a waterfall, which withsuitable setting; may-- 1 be productive of most beautiful results. In this case the'solution-container A is partially closed over at the top and the bubbleoutlet is formed at one side, as shown at a. The container may extend to any length or it may be made round or angular, so 'as to discharge the bubbles either in'a broad sheet I or on, a curve or in two or more intersecting able source of supply through pipe 5 and air from pipe 3 into duct 3*, which has a plurality of adjustable nozzles 4:, dipping at suitable intervals into the contained liquid. The bub bles issuing from orifice a fall in a broad iridescent sheet, behind which is disposed a glass, as 13, having the baflies 14 to retard the descent of the bubble-column, while the artistic effectis heightened by the illumination 'afiorded bylamps, as 15, disposed behindthe glass. By partly inclosing the top of vessel A, so as temporarily to impound the bubbles, the latter are given a chance to drain ofi the Having thus described my invention, what I claim, and desire to secure by Letters Patent is 1 In a bubble-fountain, the combination of a vessel adapted to contain liquid, an airerating vessel and means for maintaining a constant circulation between said vessel and said source of liquid-supply.

3. In a bubble-fountain, the combination with a generating vessel of an air-nozzle, a source of air-supply, a source of liquid-sup ply and means for delivering an excess of liquid to said vessel over and above the amount necessary for generating purposes and means fqr returning the excess to the source of sup- P Y- 4. In a bubble-fountain, the combination with a generating vessel, of an air-nozzle, a source of air-supply, a reservoir, connections between said reservoir and vessel for delivering a constant supply of liquid to the latter, and means for discharging the excess of liquid in the vessel back into the reservoir.

' 5. In a bubble-fountain, the combination with a generating vessel, of an air-nozzle, a source of air-supply, a source of liquid-supply, an overflow-pipe opening into said vessel, and means for adjusting the mouth of said overflow-pipe to different horizontal planes to vary the level of the liquid in the vessel.

6. Ina bubble-fountain, the combination with a generating vessel of an air-nozzle, a

blower, a liquid-containing reservoir, a pump connections between said pump and the reservoir and the vessel, an overflow-pipe connecting the vessel and reservoir, and means for operating the blower and pump.

7. In a bubble-fountain, the combination with a generating vessel, a source of air-supply and a source of liquid-supply, of an adjustable nozzle adapted to be submerged in the liquid in said vessel, an overflow-pipe opening into said vessel, and an adjustable section on said overflow-pipe to vary the volume of liquid in said vessel.

8. In a bubble-fountain, the combination of a generating vessel closed at the top and having a bubble-discharge at the side, and bubble-generating mechanism operatably associated with said vessel, said closed-top generating vessel serving temporarily to confine the bubbles to allow them to drain, and directing them to one side only of the apparatus.
